Description

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method and apparatus for upgrading a computer system, and more particularly to an upgrade method on a motherboard of a computer system. And equipment. [Prior Art] The central processing unit (CPU) is the core component of the computer system, handles the movement and calculation of data, executes computer programs, and controls devices in all computer systems. In the early computer systems, all devices in the computer system were directly connected to the central processing unit via the same busbar (s) and directly controlled by the central processing unit through commands. With the advancement of technology, the speed and life of the central processing unit

And receiving signals. The commonly used I S A interface card. A computer system provides a translation of the data produced by the above-mentioned phenomenon using a variety of different bus bars suitable for the device characteristics or limits 1 in the industrial computer industry. All bus bridges are worn out. Its function is that the commands and resources between different busbars are transmitted, read, output or transmitted. 7B 1254244 Case No. 93125038 V. Inventive Note (2) Both pass through the busbar bridges with different functions. Because of the presence of busbar bridges, there are a variety of devices in a computer system that utilize non-standard busbars. A system core logic chip is an integrated circuit component that integrates a plurality of bus bar bridges. When a computer system wants to use a device with a large number of different types of bus bars, the number of integrated circuits and the size of the motherboard are saved for the signal board of the motherboard to facilitate the signal r〇uting. Many system logic chips containing a variety of busbar bridges have been designed. System Logic Wafers consist essentially of a variety of busbar bridges. In some systems, a set of two system logic chips, called a system chipset, is used. One of the processing high-speed bus bars, such as the central processing unit bus, the system memory bus, the accelerated graphics processing bus, etc., is commonly referred to as the north bridge (n〇rth bridge), and the other processing The lower speed bus, such as the output interface, and the bus storage between the busbars of the system storage device interface bus, etc. (a bridge). Between the North and South Bridges, through a set of busbars J:, the busbars can be shared with other devices or used for transmission commands/materials between the North and South Bridges. 'Many system logic chips are even embedded inside a variety of system devices, further saving the number of components required on the motherboard. For example, an accelerated graphics processing device or system memory device can be implanted in a north bridge that already contains a busbar for use with the device, or an input/output interface device can be implanted in a south bridge that already contains a busbar for use with the device. For each device, the device is connected to the device.

The signals on the system logic bus 1 31 include the signal set of the system south bridge area 丨2 and the north bridge crystal/chip 11 2 and the system north bridge area control circuit 丨丨5. The system/system memory 11 3 is a location for the system to temporarily store the data required by all system devices including the central processing unit when the system performs an action. The system memory 113 generally stores data only when the device is powered, and the commonly used memory type is dynamic random access memory (DRAM). Depending on the system design, the system § Resonance 11 can be connected to the central processing unit 11 1 or the north bridge wafer 11 2 through the system memory sink. The system memory bus can be one or more, and individual system memory busses can be connected to one or more system memory devices. For example, some systems can have both synchronous dynamic random access memory (SDRAM) and double-difference data rate SDRAM (DDR SDRAM) or some The system has two
